In sintesi
Where a robust crust exists, the avalanche danger is low.
Steep south-facing slopes may soften if the sun is out.
Confidence
High
- We have a good understanding of the snowpack structure and confidence in the weather forecast
Avalanche Summary
No new avalanche observations were reported on Wednesday.
Snowpack Summary
A 2 to 5 cm melt-freeze crust caps the recent 20 cm of storm snow. Moist snow can be found below the surface crust.
The mid to lower snowpack contains a few crust/facet layers, including one buried in mid December, now 50 to 80 cm deep.
